Logan left Castiel's place after taking out the bullet and went straight to his place. They were currently on a holiday from school, so there was no way he could leave the house during the daytime unless he left for Castiel's place.
When he got to his place, he changed his clothes before going to bed. His Uncle was back from his meeting, but he was sure that he didn't notice him sneaking back into his place.

He left his place after breakfast. His injury was all healed up since the bullet had been taken out, but he still felt some discomfort in the place he was shot.
His father noticed this and asked if he was alright. He nodded before leaving the house.
His Aunt's husband looked at him suspiciously before shaking his head.
Castiel's house.
